Clinical analysis of blood: transcription in children of different ages

If you want to decipher the blood test from a child, you need to know that for the first time, if there is no indication for an earlier delivery, it is taken at the age of three months, then six months and a year. Also, it is necessary to take tests for almost every disease, with the exception of ARI without complications. In this case, the obtained data do not have a particular informativeness.

Children up to 13 years

The clinical analysis of blood in children is different in terms of indicators for each age. It is noted that the younger the child's age, the greater the difference. So, the difference in the analyzes taken on the first day of life and in the first month will be much greater than those taken at the age of the fifth and sixth months. According to the children's scale, the received information is considered up to thirteen years, after which the blood test is performed according to the methods developed for adults. It is believed that children, in contrast to adults, you can feed before taking blood. The main thing is that before the procedure, two hours or more have passed, since light baby food does not have a significant effect on the indicators. Drink your baby better clean water, which allows you to get the correct data on hemoglobin.

How to take blood

How is a clinical blood test done? Decipherment in children is preceded by taking material from an anonymous finger using a scarifier. Sometimes blood is taken from the vein. After that, it is studied step by step using a microscope. First, they consider blood cells , including erythrocytes, which are responsible for feeding the components of the body with oxygen. Their norm is greatest in diurnal infants (5-7 x 10 in the twelfth degree), then the amount gradually decreases, reaching 4-4.5 to the same extent at the age of 10 years. Leukocytes that protect the body from infections are also highest in the first hours of life (10-30 x 10 in the ninth degree units per liter). In school-age children, this indicator ranges from 6-10 to the same extent.

Different values for different ages

What other indicators are included in the clinical blood test? Decoding in children also includes an indication of the level of hemoglobin, which directly responsible for the circulation of oxygen. Its low level can talk about dehydration, and high implies that red blood cells are increased. For five-day babies, its rate is from 180 to 240 grams. Per liter, and for one-year-old children - about 120 g / liter.

What else is worth paying attention to when considering the result of a clinical blood test? Decoding in children shows that the youngest have a high level of reticulocytes (young erythrocytes) - from 1 to 4 percent, while schoolchildren (10 years) have such an indicator at a level of 0.4 to 0.9 percent.

In direct proportion to age, the number of platelets varies from 100 to 300 per 10 in the ninth degree at the age of up to 5 days, to 150-350 in the same degree for children at the age of one year or more. Perhaps this is due to evolution, because children begin to actively explore the world, move, get bruises and abrasions, which heal not without the participation of platelets.

Polyclinics usually provide a detailed clinical blood test. Decoding in children and adults involves specifying the parameters of the leukocyte group, which contains data on individual forms of leukocytes (basophils, neutrophils, monocytes, lymphocytes, etc.).
